Be it known that I 0. Heiroor, a citizen of the United and a pesident ofOelnnont, in the county All n and State of Pennsylvania, have inven anew and useful provement in Check-s and I do hereh declare the iollowmgto he a claim, an exact deSOllPtiOh thereof.

y invention pertains to creep-cheeks, that into any devioee forprevenlalnfilreilroad rails'irom creeping longitudi' y of, thetrecks. ct is one of the objeota of my invention to produce a creep-cheek will heeesy of manufacture and which will retain ite poeition on the ra'l. andperform its functions, regiardlees of weather ohl g l. vibration aninning of the rails, eto. It is another obiect of invention to provid acree cheokjnwhi I the work required ln :55 yin it to a rail, or removingwil be a minimum. lhither endiiurtlehl tibfiqtfi of ghee inventtiion w'appear roln 'owm peclfl' ca on taken in .oonnecticin .Lwith fileappended claims. .In order that my invention may be. fully understood, Ihave described, ample, one embodiment thereo m theio lowingspecification and shown the same 1n the a'eeompanying drawing in which:
